TO ALL WHOMIT MAY CONCERN: r

Be it known that I, BENJAMIN F. WHEELER, `ofGalais, in thelcountyof Washington, and State ofVermont, have invented a new and improved Self-Acting Brake for Carriagesand Sleds'; and I do hereby declare that the following is a. full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

Figure 1 is a perspective viewof my invention, one of the hind wheels beingV removed to showtheV construction. Y i

Figure 2'is a perspective view, showing the under side of the rocker-plate.

Similar letters of reference indicate corresponding parts in the two figures..

This invention relates to an improved self-acting carriage-brake, and it consistsin providing the brake-bar with a. handle or bar, extending to the forward bolster or rocker, and so connected to the reach and king-holt that, as the hind wheels of the wagon are pressed forward, the bar will slide upon the reach, and the brake shoes be brought in contact with the hind wheels. -It also consists `in a latch or catch attached to the forward bolster for controlling the operation of the brake, and in the means employed to prevent Athe backing ofthe carriage in ascending a hill. i

p To enable others skilled in the art to make anduse my invention, I will proceed to describe its construction and operation. Y

I construct the wagon with one, two, or three reaches, connecting the hind wheels with the rocker, as represented in the drawings. Beneath the rocker there is a rocker-plate, with a holerin `the centre ofthe same, about one inch by about three inches, through which` the king-bolt, that is attachedto the handle of the brake, passes. The brake extends across the reaches, in front of the hind wheels, with dogs about one or two inches distant from each wheel, represented by the letter a in the drawings. A handle extends from the middle of the'brake 'to within a few inches of' the rocker, and beyond a hole in the middle reach, corresponding in size andshape i with the hole in the rocker-plate, and a strap of iron'or other metal, about two and a half to four nchesiwide, extends from'near the end of thewooden part of the handle through the rocker, and'down round between the 5 rocker and rocker-plate, backas far as lthe other end of the strap, and a boltpassesthrough the hole in the reach above mentioned, connecting the two ends of the strap, and is represented bythe letters b B in the draw-` 4 y ings. The strapv projects about two inches in front of the rocker, when the brake is not operating upon4 the wheels. A movable wedge or key, represented by the letters C c C in the drawings, is attached to the front of" the rocker in such a manner that it may be slid into the hole between the strap and the rocker to facilitate the u backing of the carriage, bypreventing the operation ofthe 'brake The strap plays back and forth in thef .rocker to the extent of the hole in the rockerjplate, 'thereby causing the `brake to operate. The letters GG represent the rocker-plate, the letter I represents` the hole in the rocker-plate, and the letter H the king-bolt. On the inside of one of the hind wheels I put a rag-wheel, lrepresented by the letter D inA the drawngspwith a dog, represented by the letters e E, to prevent the carriage from running back, when I desire-to go up-hill, to which dog I attach a spiral wire, represented by the letter F, to regulate the dog by means of 'the' brake. l

What I claim as my invention, and desire to secure by Letters Patent, is y f 1. The movable handle of the brake, in combination with the slotted central reachme'tal loop and strap B b, forward slotted rocker and the king-bolt, and slotted-rocker-plate, substantially :ss-described, for the lpurpose speciiied. f

2; dIn combination with the above, I claim the sliding key C c C, substantially as described, for the purpose speeiie Y I 3. In combination witha wagon-brake, the rag-wheel D, dog E, and coiled spring F, substantially as" described, for the purpose specified. A
